## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** Long descriptions in `create_meme` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,009 characters long, over the 2,000 this check looks for.

description ends: "...data of the image item in result.content from base64 into a file for the person."
```

- **warn** Annotations that disagree with the tool in `create_meme` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_meme" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_meme" says "create": a word for a change.
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_meme`

- The name "create_meme" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info long-description, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Create a meme on exactly one of: template (a catalog id), image (your own picture in base64 or a data: URL; JPEG, PNG, WebP or GIF, up to 5 MB and 25 megapixels (16 for WebP, 8 for GIF, less for a large progressive JPEG), 100 px or more a side, at most 4:1; a GIF gives its first frame) or image_url (an https address the server downloads). Your own picture is laid out like a template, with slots found in it (see get_template). Captions go in slots, classic top/bottom positions or boxes (fractions of the image, x and y the top-left corner), plus optional author, emojis, stickers, shapes with text and a filter. The server fits and colours every caption, and may write a line break (\n) into a returned caption text, to keep a short word or a number off the end of a line, to keep a quote on one line or to break a long word after an underscore: a returned text sent back as it is comes out the same. With author, the handle goes in the first corner free of other layers, and of faces when it can: bottom right, top right, bottom left, top left. When a top and a bottom caption leave no corner free, the bottom one moves up a little to free one for the handle, given or saved by the person in the studio. Returns the link that opens the meme in Meme Studio (an editor link, never an image source), what each caption got, warnings and a picture: picture "preview" (800 px to check, the default with a template) or "final" (the finished meme at 1200 px with the invisible watermark, like the studio download; the default with your own picture, because the link cannot carry it and only reopens the captions). For a file on disk, with a terminal, do not paste its base64 yourself: pipe the tools/call JSON from the shell into curl --data-binary @-, without a temporary copy of the picture, to the server's /mcp (Content-Type: application/json, Accept: application/json, text/event-stream; no initialize needed), then decode the data of the image item in result.content from base64 into a file for the person.
```

### `popular_templates`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Templates people choose most in Meme Studio: trending this week or most used overall.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_template`

- The name "get_template" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Details of one template: names, what it is used for, tags, size, whether it is animated and its slots (the boxes where captions go). Each slot has fits_chars, about how many characters fit in it at a good size (0 is a small slot for a word or two): keep its caption under that or the text comes out small. With image: true (or show_slots: true) it also returns the picture with the slots outlined and numbered. Instead of template, give your own picture as image (base64) or image_url, as in create_meme: you get the slots found in that picture, the same ones create_meme uses with it.
```

### `search_templates`

- The name "search_templates" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the Meme Studio catalog by name, keywords or what the meme is used for (intent), in Spanish or English. Best matches first, each with what it is used for.
```

## Claude Code permissions
